Hello Sir:
We use the BQ28z610 EVM testing the power consumption.
We use 1 cell and the cell voltage is 3.6V.
When there is no communication and VPACK, the Iq is about 200~270uA.
That is not match the datasheet that datasheet shows the Iq will be 100uA in sleep mode.
If we set [IN_SYS_SLEEP]=1, the Iq will be under 100uA.
Is it acceptable? Is it a normal reponse?
Please refer the gg file.
If you need other information please kindly let us know.
Thanks a lot.
Hello Kang Kang:
We try to measure the Iq again, but the result is not good.
Please refer the gg file as attachment and tested figure as below.
1. Circuit connection of EVM and meter.
2. After 30 mins, the measure result of current meter.
Also we check the CFET and DFET that are still has output voltage. (SLEEPCHG]=0)
If we setup the [IN_SYSTEM_SLEEP]=1 and retested again, after 30 seconds, the Iq will down to 90uA.
Is it a normal respond?
Or should I change a IC and retest again?
Please let us know your recommendations.
Thanks a lot.
